I probably should have kept my mouth shut, since I don't actually know
what you're looking for, nor do I have any good suggestions for
alternatives. That said, my packaging experience leads me to strongly
prefer build systems that work in "standard" ways, and don't for
instance require in-tree builds for linking applications, which EPICS
currently requires (modulo the packaging ninjitsu accomplished by the
EPICS Debian packagers).
Thanks, Jamie.
Based on all of the feedback, I will use a different technique to build kernel modules for multiple architectures outside of EPICS.
However, for my user space libraries I will stay with the EPICS Make system as it is very convenient and points nicely to my cross-compilers (i.e Tool Chains)
Cheers,
